I finally got an FFT algorithm working today and was able to convert it to a frequency scale. In addition, I need to add a short method to apply windowing functions to the audio signal before running the FFT. I would also like to add a method to "reset" the DFT so the same audio file does not have to be loaded again to run another FFT of a different sample size or with a different windowing scheme. I also should add a few more error catching and checks into my program to make sure it won't crash.
Tonight I am going to begin reading up on the Constant Q transform and will continue research on it through the end of the week. By mid-week next week, I will hopefully know enough about it to be able to start coding the transform. Tomorrow I plan on adding the last few finishing touches on my FFT and start research on the Constant Q transform.
Sounds good. Keep adding comments as you decipher the constant Q literature. Should be interesting.
